A continuous effort is made to make these sensors smaller, better and cheaper. This allowed for new applications that caused the market to grow exponentially in recent years. Pressure sensors have recently found implementation in the mobile sensor market, however they require lots of fabrication steps making them relatively expensive. Due to its exceptional properties, graphene can be used as both an electrical and mechanical element reducing the amount of fabrication steps needed to build a pressure sensor. Using this principle, concepts for an absolute (atmospheric) pressure sensor and pressure difference (gage) sensor were developed. Novel analytical solutions were developed and compared to existingmeasurements of similar devices or to numerical simulations. It is found that these devices will not only be smaller and cheaper, but also have a larger bandwidth and less sensitivity to mechanical disturbances. The thermal noise of these devices is orders of magnitude lower than similar silicon based devices, therefore it is expected that graphene based sensors will meet the demands on accuracy, resolution and signal-to-noise ratio of current high-precision pressure sensors. It is concluded that graphene based resonant pressure sensors have the potential to meet the future mobile market demands.
